Procedure

To a rt solution of (3S,4S)-3-amino-1-((3-cyclopropylquinolin-4-yl)methyl)-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepine-7-carbonitrile dihydrochloride (126 mg, 268 μmol) in DMF (893 μl) was added Boc-N-methyl-L-alanine (59.9 mg, 295 μmol), N,N-diisopropylethylamine (232 μl, 1.34 mmol), and HBTU (112 mg, 295 μmol). The reaction was stirred at rt for 1 h, then diluted with EtOAc, washed with H2O, sat. aq. NaHCO3, and sat. aq. NaCl, dried over Na2SO4, filtered, and concentrated. The crude material was purified by flash chromatography to provide tert-butyl(S)-1-((3S,4S)-7-cyano-1-((3-cyclopropylquinolin-4-yl)methyl)-4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-3-ylamino)-1-oxopropan-2-yl(methyl)carbamate (144 mg, 92%) as a white solid. MS m/z 583 (MH)+.
